Use an altar only when its visible effect supports the current run and the downside does not violate your exit rule; never price an unknown blessing as guaranteed value.
What is verified
- Official materials name Midas, size-changing, manic, and depressed altar-related states.
- Altars are described as radically altering playstyle.
- A complete current effect, duration, and probability table is not officially published.
Read the current stake first
An altar decision depends on what is already in the bag, remaining health and resources, and route familiarity. The same uncertain effect is easier to justify early in a low-value learning run than after finding a milestone item.
If the displayed text does not make the tradeoff clear, preserve the haul. An unknown state should not be treated as a free upgrade simply because other altar outcomes can be powerful.
Separate named states from exact mechanics
Midas, size changes, manic, and depressed states are official examples, but their exact coefficients, durations, and interaction rules are not supplied in the store description. Describe only what the current interface or controlled observation supports.
Demo Update 2.0.1 documented prayer and Midas text corrections, which shows why old screenshots can mislead. Recheck current wording before building a guide or decision around a demo-era effect.
Recalculate the exit rule afterward
A beneficial state can encourage overconfidence, while a downside can make the planned route unacceptable. Immediately revisit health tolerance, combat pattern, mobility, and haul threshold after accepting any effect.
Record the altar, visible text, biome, and outcome only if doing so is safe. Several consistent observations can support editorial guidance; a single dramatic result remains an anecdote.
